Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems with electronic visual displays face challenges in effectively cooling these displays without increasing size, cost, or power consumption, while also simplifying maintenance and minimizing noise and condensation.
Innovation Solution
A cooling system that utilizes a double-walled elevator car design with fluid flow paths to cool electronic visual displays, including a first flow path to cool the passenger space and a second flow path that directs fluid through a gap between the display and the inner wall, using fans to manage airflow and a controller to activate fans based on temperature or display activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional ventilation means are used to discharge heat from displays, then heat removal is achieved, but the system becomes bulky and complex
Solution Approach 1:
The cooling system is nested within the existing double-walled structure of the elevator car. The gap between the inner and outer walls serves as the cooling channel, eliminating the need for separate external cooling components. This nesting approach allows heat removal while maintaining a compact and simple system architecture.
Solution Approach 2:
The gap between the double walls serves multiple functions: it provides structural insulation, noise reduction, and now also serves as the cooling flow path for electronic displays. This multi-functionality eliminates the need for dedicated cooling structures, reducing overall system complexity.
2Temperature
If cooling systems are added to electronic visual displays, then heat is removed, but noise increases
Solution Approach 1:
The fluid flow path is nested within the existing double-walled structure, utilizing the gap between walls as the cooling channel. This eliminates the need for separate external cooling ducts and reduces the number of moving parts that generate noise.
Solution Approach 2:
The double-walled structure acts as an intermediary that provides both structural support and a cooling flow path. The gap between walls serves as a passive cooling channel that reduces noise from fans while maintaining cooling effectiveness.
3Temperature
If cooling systems are implemented, then heat is removed, but condensation occurs
Solution Approach 1:
The double-walled structure with its insulating gap acts as a thermal intermediary that prevents rapid cooling of the inner wall surface. This gradual temperature reduction minimizes the temperature differential that causes condensation, while still achieving effective heat removal from displays.
Solution Approach 2:
The insulating gap in the double-walled structure provides beforehand cushioning against condensation by maintaining a more stable thermal environment. This prevents the rapid temperature changes that would otherwise lead to condensation on the inner wall surface.
4Temperature
If multiple cooling components are added, then cooling effectiveness improves, but maintenance difficulty increases
Solution Approach 1:
The double-walled structure serves multiple functions including structural support, insulation, noise reduction, and cooling. This consolidation reduces the number of separate components that require maintenance, simplifying the overall system while maintaining effective cooling.
Solution Approach 2:
The cooling system is nested within the existing double-walled structure, utilizing the gap between walls as the cooling channel. This eliminates the need for separate external cooling components, reducing maintenance requirements while maintaining cooling effectiveness.
